To ALLwnoM IT MAY coNeERN ,v j f y Be `it known that I, NATHANIEL ROWE, of Emmittsburgh, in theV county of Frederick, and State of Maryland, haveinvented certain new and useful Improvements in Harvesters and I do hereby declare that the following is a full, clear, and exact description of the same, referencebeing lhad to Athe anneired drawings, made partof this specification, .j j l 'j v Figure 1 is a perspective view, part of the casing being represented as broken away, so as to Show the intern'al arrangementof the machinery. I i

Figure 2 is a'vertical-sectiou through the centre of the axle. Figure 3' is a side elevation of the brace of the tongue and the support of the seat.` Figure 4 is a vertical longitudinal section, showing the pitman and the mode of its arrangement.` Figure 5 is a section of one of the wheels. I Tn the di`erent gures the same letters refer to identical parts. My improvement relates to the kind of machine known as a twowheeled mower. j. A A are the ground wheels, the hub of which, C, is constructed with a recess in its inner face, containing the ratchet-wheel B, the detent B1, and coiled-spring B2. This face of the wheel fits snugly against the ange p C', attached to the axle. The ratchet is so arranged that the wheel will turn on the axle when the wheel is revolving backward, and with the' axle when revolving forward. On the axle D is keyed the spur-wheel F, working into the teethl of the pinion Gr. This pinion communicates motion to rthe countershaft I, upon which it moves, in a groove, so as to be thrown in or out of gear, as desired, by the lever G. To this counter-shaft is keyed the spur-wheel H, the teeth of which communicate motion to the pinion K, which turns freely upon the main axle D, and carries with it the face-wheel L, working into the bevelled pinion M,Akeyed on to thc shaft N,

the otherrend of whichl carries the crank-wheel O, connected with its pitman Q, which gives motion to the knives in the ordinary manner. This gearing is compactly disposed at the middle of the axle D, and inniedi atcly under the driver. It is entirely enclosed in the case E, which sustains the journals of the counter-shaft, and also extends along the entirelength o f the shaft N. Within this casing E, at the part marked `lil/,is placed the piece P, which ts snugly within the case, and has two bearingsone at either end-carrying the shaft N.

It is secured by a projection passing through'the lower side of, the casing, at E', having a slot, P', for receiving `a key which will retain it firmly in place. By removing this key, and detaching the pitman, the piece P can be removed, together with the shaft N, bevel-wheel M, and crank-wheel O. i The cuttcr-bar is hinged to thelower end of the brace W, which is supported by the brace W, which is attached to the axle D by a collar, which permits it to turn freely in front of the lower extremity of the brace W, projectsthe curved shoe R through a slot in which passes the wheel R2. This wheel is adjustable, supported by the lugs R1. The shoe Rturns up in front, and has a slot nearY its upper extremity, R3. S is a lever, shaped substantially as shown. It is suspended by a wrist T', projecting from the brace of the shaft N. The portion of the lever containing this slot is bent, as shown in the drawings. The leg S of this lever projects to the front, and terminates in a hook passing through the slot R5. The leg S2, passing directly down, is bent at the foot at nearly or quite a right angle to the front, and this foot rests upon the L shaped heel of the cutter-bar Y. This foot prevents any torsion of the cutter-bar and ,its support W. By drawing back the upper end of the lever S, the entire cutter-bar and its attachments may be raised for passing any obstacle, the casing turning on the axle, the adjustable bar :c rising througha slot in the end of the tongue T. When the Ymachine is to be transported without cutting, the cutter-bar and its` attachments are raised by theA lever S, and Vsecured by a pin inserted in the bar zu, below the tongue; thc pitman being disconnected, and the levcr'S detached, the cutter-bar may bc raised, turning upon its hinge, and rested against thc brace of the tongue; the lover S, replaced, will prevent 'its falling outwards. The casing E, when it rests on thc axle, has a bearing, with an outwardly-projecting flange, E2, on which rest the ends of the braces of the tongue. These .braces have a collar, to which is permanently attached the end of the standards U, as shown infig. 3, the whole being `in one piece. These standards j are bent over the ends of the casing, and turned up so as to receive thc seat V. Thc scat rests upon two pipes,

one of which is shown in section, in iig. 1. These pipes contain spiral springs V2, which, resting upon thel upper ends of thcvstandards, which give elasticity to the seat. The seat is secured by a chain or athen device. VI

is the footboard,'resting upon the braces of the tongue. The detached drawing I represents a tubular hearing,

inserted in the side of the casing E, on each side, for the purpose of receiving the journals of' they countershaft' I. It will be obsei'ved that the entire machine is so joined that not a holt enters into the entire construction. That portion of the casingr represented as broken, is made separate, so as to he readily detachable, to give access to thegeax'ing and shaft N.

1. I claim arranging thc entire gearing at the centre' of the machine and surrounding it with a casing E,

the gearing and casing being constructed and arranged substantially as set forth.

2. I claim the detachable pice P, in combination with the shaftN, and casing E, when the lattea` is constructed with a movable cap that -covers the gearing on the axle, and the piece P, substantially as and for the purpose s'et forth.

3. I claim attaching the braces of the tongue T, by a collar, to a flange E2, projecting from and being a part of the casing E, substantially in the manner set forth. l, 4.y claim thecomhination of the drivel-'s seat V,`and springs V2, with the standards U, when the same are permanently attached to. and on the opposite side of the axle from, the braces of the tongue.

5. I claim thc slotted and bifurcated lever S, when connected with the cutter-bar in front and rear,` substantiallyfas-and for the purpose set forth. v l

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses.
